Why Banks Must Integrate Investing Into Mobile Apps to Win Gen Z and Millennials

For years, traditional banks and credit unions competed for younger customers by offering high-yield checking accounts, sleek debit card designs, and attractive rewards programs. However, new research indicates these traditional acquisition tactics are losing their edge. The financial behavior of younger generations has fundamentally shifted, and traditional institutions must adapt to survive.

A study by Cornerstone Advisors reveals that “Zillennials”—the micro-generation bridging Gen Z and Millennials—increasingly manage their money by constantly shifting funds between checking, savings, and investment platforms. Fintech companies have successfully capitalized on this trend by creating seamless, user-friendly experiences that make investing as effortless as peer-to-peer payments. As a result, deposits that once sat securely in traditional bank accounts are migrating elsewhere.

The solution for traditional financial institutions is not to reinvent the wheel, but to meet customers where they are. By embedding wealth management and investing tools directly into their existing mobile banking apps, banks and credit unions can eliminate friction and retain younger customers.

The Changing Dynamics of Money Movement

Historically, securing a customer’s primary checking account and direct deposit was the ultimate goal for banks. It served as the anchor relationship, opening the door for future profitable products like mortgages, car loans, and wealth management.

Today, that anchor is slipping. The Cornerstone Advisors study highlights a staggering statistic: 56% of new checking and payments accounts in 2025 were opened with fintech providers, up from 49% in 2024. Younger consumers are not necessarily dissatisfied with traditional banks; rather, they prefer the fluid experience offered by modern digital apps.

Zillennials do not view saving and investing as separate, occasional events. Instead, they actively manage their funds daily, moving capital into stocks, ETFs, robo-advisors, and digital assets. If a bank does not facilitate this movement internally, the consumer will simply transfer their money to an external provider.

Investing Has Become an Everyday Banking Feature

Investing is no longer a milestone reserved for later in life. Today, nearly half of Zillennials own stocks or ETFs through digital platforms, and another 22% utilize robo-advisory services. Crucially, 43% of these younger consumers have moved deposits out of their traditional bank accounts over the past year specifically to fund these investment vehicles.

This trend presents a massive opportunity for traditional financial institutions. Research shows that three-quarters of younger investors would prefer to invest directly from their primary checking accounts. The demand for a consolidated financial hub is clear: 67% of Zillennials state that an all-in-one mobile app combining traditional banking with investing capabilities would make a financial institution significantly more compelling.

Navigating the Crypto Landscape

While cryptocurrency remains a hot topic—with one-third of Zillennials holding digital assets—banks should not treat crypto as a standalone solution. Offering a isolated cryptocurrency wallet or a separate digital asset app will not solve the acquisition challenge.

Instead, younger consumers view crypto as just another asset class within a broader, long-term wealth portfolio, alongside traditional stocks and mutual funds. Financial institutions should prioritize traditional investing capabilities first, treating cryptocurrency and stablecoins as integrated extensions of a comprehensive wealth-building platform rather than the main attraction.

Frictionless Lessons from Fintech Giants

To compete effectively, banks and credit unions must study the playbook of successful fintech platforms like Robinhood and Coinbase. The success of these companies lies in their dedication to reducing consumer friction:

• Fractional Shares: Robinhood lowered the barrier to entry, allowing users to start investing with just a few dollars, eliminating the need for large starting balances.
• Contextual Education: Coinbase integrated learning modules directly into the user journey, rewarding users with small asset balances for completing short quizzes.

Instead of burying financial education in static resource libraries, traditional institutions should embed guidance directly at the point of decision-making. Simple, in-app prompts—such as identifying surplus cash and suggesting a recurring transfer to an investment account—can guide consumers toward better financial habits without overwhelming them with information.

Strategic Priorities for Banking Leaders

To win and retain the next generation of deposit holders, retail banking leaders must prioritize the following strategies:

• Consolidate the Experience: Integrate investment, robo-advisory, and traditional banking tools into a single mobile application rather than forcing users to navigate disconnected portals.
• Leverage Fintech Partnerships: Building these complex digital platforms internally can take years. Partnering with specialized fintech providers can dramatically accelerate time-to-market.
• Automate Wealth Building: Encourage consistent investing through micro-actions, such as debit card round-ups, automated recurring transfers, and milestone-based contribution matches.
• Deliver Embedded Advice: Offer personalized, contextual financial guidance at the exact moment a customer is making a financial decision within the app.

The ultimate metric of success in modern retail banking is shifting. It is no longer just about who holds the consumer’s deposits, but who provides the most seamless environment to spend, save, and grow those funds. Banks and credit unions that unify these experiences will build lasting loyalty with younger consumers before they transition to fintech platforms as their default financial home.
